簡短描述
型態特徵 | 形態測量圖
脊椎骨: 31 - 34. Diagnosis: This species can be distinguished from all congeners by the presence of a single well-defined, round to horizontally oval humeral spot, similar to the one found in species of the Astyanax bimaculatus (Linnaeus) complex (vs. humeral spot absent, double, or variously developed, never round to horizontally oval). It can also be distinguished from its congeners, except H. reticulatus Ellis, by the combination of a reticulate dark pigmentation pattern, a broad, horizontally-elongate caudal-peduncle blotch, a narrow dark stripe extending along the central caudal-fin rays, 5 or 6 horizontal scale rows between the dorsal-fin origin and the lateral line, 4 or 5 horizontal scale rows between the lateral line and the pelvic-fin origin, and 15-20 branched anal-fin rays. Hyphessobrycon langeanii can be distinguished from H. reticulatus by the possession of a conspicuous, dark round to oval humeral spot (vs. relatively faint, vertically-elongate humeral spot), a horizontally-elongate caudal peduncle blotch (vs. vertically-elongate caudal peduncle blotch), the midlateral dark stripe relatively wide and faint (vs. midlateral dark stripe extremely narrow and well-defined), and infraorbitals 3 and 4 co-ossified (vs. separated) (Ref. 52338).
鑑別: 這種能被與所有的同類區分藉由有一很清晰, 水平橢圓形的肩部斑點的圓, 類似 Astyanax bimaculatus(林奈) 複合體的這一個被發現於的種.(vs. 肩部的斑點不存在, 加倍, 或各種不同地發展的, 從不圓的到水平橢圓形) 除了 H. reticulatus 艾理斯以外,它也能被與它的同類區分, 藉由網狀深色的顏色圖案的組合 , 寬, 水平地-細長的尾柄斑塊, 一條延伸的狹窄深色的斑紋沿著中央的尾鰭鰭條 , 背鰭起源和側線之間的 5 或者 6 水平的鱗片列 , 側線和腹鰭起點之間的 4 或者 5 水平的鱗片列,而且 15-20 分枝了臀鰭棘條。 Hyphessobrycon langeanii 能被與 H. reticulatus 區分被擁有對橢圓形的肩部斑點 (vs. 相當模糊又細長垂直的肩部斑點) 的一個顯著又深色的圓, 一水平地-延長尾柄斑塊 (vs. 細長垂直的尾柄斑塊), 側面中央的深色斑紋相當寬而模糊的 (vs. 側面中央的深色斑紋非常狹窄而且很清晰), 與眶下骨 3 與 4個共鈣化了 (vs. 分開).(參考文獻 52338)
